Bakuman Wiki

Hisashi Sasaki (Born February 22, 1963 in Gunma-ken, Japan), was formerly the Editor-in-Chief at Weekly Shōnen Jump before he was transferred over and became the Editor-in-Chief of the newly created monthly manga magazine Hissho Jump.


Sasaki wears glasses and has a small moustache. He wears professional clothing, unlike the other editors who wear casual clothing in the office, showing that he may believe that clothing reflects how one thinks.


Sasaki seems very wise to how manga works, and for the most part is very level-headed. Once he makes a decision, he sticks to it until convinced otherwise, be it putting Ashirogi Muto on hiatus until they graduate or voting against PCP 's serialization. It was said by Heishi that Sasaki was hotheaded in his career as a mangaka like Fukuda, often shouting loudly that "editors don't know anything."

Sasaki believe that a Mangaka blame their editor or the editorial department for their lack of success is cowardly When Takahama ask Sasaki to Change Editor because he believe that Miura is not let him draw what he want Sasaki state that Takahama is admiting that he lack enough talent and state that any Good Shonen Manga will be accepted as is it and it not because he does not have the abillity to do so and will not change Takahama editor and it not because he get Miura as his editor not because he was new state it applied to new and old alike and advise him to create an manga that will make Miura agree

He used to work alongside Mashiro Nobuhiro (being his editor at one stage) to whom he had great respect for and still does to the present day. He was very sad to be the one who had to break the news to Nobuhiro about the end of his contract. His catchphrase "Manga just needs to be interesting. If it's interesting, it will get serialized" were the last words Nobuhiro ever spoke to him and it is those words that seem to have had a great impact upon his personality. His respect is perhaps best demonstrated when he himself decides to give feedback to both Mashiro and Takagi, knowing Mashiro is the nephew of Nobuhiro.
